An optional Fibre Channel host interface adapter can be installed in a node canister. All node canisters in an enclosure must contain the same optional components. The node canister has room for one host interface adapter. Its location is known as adapter slot 1.

Each node canister contains a battery that can power the canister while it stores cache and system data to an internal drive in the event of a power failure. This process is known as a fire hose dump.
